Dual-Band USB 3.0 Adapter

The TP-Link Archer T3U Plus is a USB 3.0 wireless adapter that adds dual-band Wi-Fi to a desktop or laptop. It connects through a standard USB port and supports data rates up to 1.3 Gbps across 2.4 GHz and 5 GHz bands. An external high-gain antenna is included to improve reception and transmission strength. The device draws power directly from the USB interface.

For Upgrading Older PCs

This adapter suits users who need to add modern dual-band wireless to a system lacking built-in Wi-Fi or equipped with an older single-band module. It works with Windows 10, 8.1, 8 and 7 on both 32-bit and 64-bit installations. Buyers who require Bluetooth connectivity or an internal PCIe card with multiple antennas should consider a different form factor.

AC1300 Speed Rating

The key specification is the AC1300 class rating, which delivers 867 Mbps on the 5 GHz band and 400 Mbps on the 2.4 GHz band. This throughput level determines whether the adapter can match the performance of a compatible dual-band router. Actual speeds depend on the host system, router capabilities and local radio conditions.

Questions about this item

Should I pick the 2.4 GHz or 5 GHz band for my Archer T3U Plus?

The adapter runs both bands simultaneously. Use 5 GHz for up to 867 Mbps when close to the router, and 2.4 GHz for up to 400 Mbps through walls or at longer range.

What does the AC1300 rating actually deliver on my PC?

AC1300 is the combined theoretical ceiling of 867 Mbps on 5 GHz plus 400 Mbps on 2.4 GHz. Real-world throughput will be lower and depends on router capability, distance, interference and USB 3.0 bus limits.

Will the USB 3.0 interface bottleneck the 867 Mbps 5 GHz link?

USB 3.0 provides up to 5 Gbps signalling, well above the adapter's 867 Mbps 5 GHz maximum, so the interface does not cap the wireless speed in practice.
